Title: Process for converting iron oxide to iron carbide employing internally generated carbon oxide as the carbiding agent
Inventor: STEPHENS FRANK A
IPC: C01B31/30
Filed: 1997-02-05
Abstract: A process for converting iron oxide to iron carbide using hydrogen as a reducing gas. Water is generated by the reduction of the iron oxides using hydrogen.
